Pre‐treatment of Waste Foundry Sand Via Solidification/Stabilization
CLEAN – Soil, Air, Water, 2012 AbstractThis study was performed to propose a suitable treatment for waste foundry sand (WFS) before persistent disposal. It was observed that solidification/stabilization (S/S), which is the common pre‐treatment method because of its comparatively easy and inexpensive applicability, can treat WFS including dissolved organic carbon (DOC) above ...
